. HYDRANT.

SPECIFICATION forming part of Letters-Patent No. 415,119, dated November 12, 1889.

Application tiled June 20, 1889. Serial No. 314,982. (No model.)

To @ZZ whom t may concern,.-

Be it known that I, THoMAs S. MoELHosE, of Paterson, in the county of Passaic and State of New Jersey, have invented a certain new and useful Improvement in Hydrants, of which the following is a specification.

`My improvement consists in so constructing a hydrant that it will be practically nonfreezing.

I will describe in detail a hydrant embodying my improvement, and then point out the novel features in the claim.

In the accompanying drawings, Figure `1 is a side elevation, partly in section, of a hydrant embodying my improvement. Fig. 2 is a vertical section, on an enlarged scale, of the lower portion of the hydrant. Fig. 3 is a detail view of a valve-chamber. Eig. 4 is a detail view of a coupling-piece, constituting a wrench, acting in conjunction with said valvechamber.

Similar letters of reference designate corre- 2 spending parts in all the gures.

A designates a barrel composed, as here shown, of sections a Ct a2, having a screwthreaded connection vwith each other. EX- teuding centrally through the barrel A is a movable pipe or series of pipes and couplings, through which the water is to be discharged. This pipe comprises a section B, which section extends centrally through a valve-chamber C. The valve-chamber C is rigidly secured to the section a2, near the lower end of said valvechamber, as here shown, by means of screwthreads. The section B, as it is moved up and down in conjunction with the rest of the pipe, with which it forms a part, is provided with suitable stuffing-boxes h b', arranged at the upper and lower ends of said valve-chamber respectively. Between said stuffing-boxes the valve-chamber is hollow, and is provided with a valve-seat b2 for a valve b3, arranged upon the section B of the movable pipe. Above the valve b3 there are arranged in the section B openings h4. lVhen the valve is upon its seat b2, these openings will be closed to the admission of any water which may be within the valve-chamber C. When, however, the section B has been moved downwardly so as to uncover said openings b4, water which may be in the valve-chamberv C will pass through said openings into the section B, and thence upwardly through the pipe of which it forms a part. Tater is admitted to the valve-chamber C through suitable openings c, 5 5

formed in the wall of the valve-chamber, which openings afford communication with an annular passage D, formed or cast in the section a2 of the barrel A. Vater is admitted freely to the. annular space D from a pipe E, 6o

communicating therewith. I have shown a compressed-air chamber F, of `ordinary construction, upon the section a2 and communicating with the passage D.

B designates another section of the mova- 6 5' ble pipe, which section has a screw-threaded connection near its lower end with a couplingpiece G, withwhich coupling-piece the upper end of the section B of the pipe also has a vscrew-threaded connection. A passage is thus 7o pass freely around through said annular pas- 8o sage. To the upperV portion of the couplingpiece'G is connected a section B2 of the movablepipe, which section also communicates with the annular passage g. The section B2 extends upwardly through the section Ct of 8 5 the barrel and through a chamber e upon the upper end of the section ct', in which is arranged a coil-spring f. The coil-spring f surrounds the section B2 of the pipe and bears at one end against the upper end of the sec- 9 0 tion ct of the barrel and at its other end against an abutment d, secured upon the section B2 of the pipe. The abutment d in this instance consists of a hollow cap which eX- tends over the chamber e, and may slide freely up and down thereon during the movements of the movable pipe. The upper end of the cap d, which surrounds the section B2 of the pipe, is externally screw-threaded, and

is preferably conical in shape and split vertiloo The coupling-piece G has 7 5 barrel A is a waste-water chamber J.

cally. A nut d, when screwed down upon said screw-thread, operates to clamp the cap cl tightly upon the sectionA B2.

ll designates a lever fulcrumed upon the section. a of the barrel A. A portion h of the lever Il constitutes a handle. A portion 7L" extends through a suitable opening in the section ct of the barrel and into a transverselyexteuding passage-way h2, formed in the coupling-piece G. The portion h of the lever II is rounded at its end. li" the handle 7i of the lever H be grasped and swung upwardly, the movable pipe will be moved downwardly against the resistance of the spring F, and will cause the valve b3 to be moved from its seat. Vater will then flow in through the openings b4 up through the section B, the couplin piece G, the section l', the coupling-piece G2, and thenceout through the section B2. l have shown upon the section a of the barrel a catch I, pivoted upon said section and adapted, when the lever ll has been swung, as described, to engage a notch z' in the lever and maintain such lever in an elevated position and the valve if; off from its seat, until it has been released from engagement with said notch. As soon as released fromsuch engagement or the hand is removed from the lever li, the spring f will operate to move the movable pipe upwardly, and thus reseat the valve b3 upon its seat, shutting oi'f the iiow of water through the pipe.

In the lower portion of the section et? of the The section B of the movable pipe extends into this miste-water chamber. Said chamber at its lower end is provided with an outletj, shown as formed in a union To the'union' j? is connected a waste-water pipe J". l prefer that the waste-water pipe J should be provided with a U-shaped trap j, which may be of ordinaryconstruction. Upon the lower end of the section B is a valve J2. XV hen the movable pipe is moved downwardly, as has been described, the valve J2 will seat itself upon the inner end ot the union jig, which thus acts as a valve-seat and will close the outlet-openingsj. lVater can then iiow from the wastewater chamber J out through the waste-pipe. lVhen, however, the movable pipe is moved upwardly, so as to seat the valve U again upon its seat, any water which may remain, will ilow out through openings Zin the lower portion of the sectionB into the waste-water chamber J, and thence out through the waste-pipe J and to waste. Thus it will be seen that no water will be left standin g in the movable pipe,which in cold weather may freeze and prevent the flow of: water.

Of course it is to be understood that the section a2 of the barrel will be arranged suiiiciently below ground to prevent freezing at that point, and also at the waste-pipe, the only danger from freezingbeing with the npper or outlet portion ot' the hydrant, which by my improvement is obviated.

In order when desired to freely remove the valve-chamber C and the movable pipe, it' for any reason it. should become necessary, I have provided the coupling-piece G with verticallyextending slots fn, into which slots extend lips o upon the upper portion ot' the valve-chamber C. By this means, it' the movable pipe be rotated from its Lipper end portion, the valvechamber (l may be unscrewed from the section a2 of the barrel, and the whole may be thus withdrawn. By the same means it may be again inserted and secured to the barrel.

NVhat I claim as my invention, and desire to secure by Letters Patent, is-

In a hydrant, the combiinltion, with a valvechamber, of a longitudinally-movable pipe extending through said valve-chamber, an inlet for water com munieatin g with said valvechamber, a valve on said movable pipe ar ranged within said valve chamber and adapted to open and close communication bctween said valve-chamber and said movable pipe, a second valve also on said. movable pipe and below the valve-chamber, a waste-water chamber below the valve-chamber, into which said movable pipe extends, and an outlet-passage for the waste water below said movable pipe, closed by said second-named valve when the lirst-named valve is opened, and opened when said first-named valve is closed, substantially as and for the purpose specified.
